SPECIFICATION forming part of Letters Patent No. 422,363, dated March 4,1890.

Application filed June 24, 1889- Serial No. 315,381. (No model.)

Be it known that I, SAMUEL R. BATESON, a citizen of the United States,residing at Deitroit, in the county of Wayne and State of Michigan, haveinvented certain new and useful Improvements in Capsule-Machines; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which.it appertains to make and use the same, refer- .ence being had to theaccompanying draw- .ings, and to the letters and figures of referencemarked thereon, which form a part of this specification.

This invention relates to an improvement in capsule-machines, in whichthe main frame of the machine carries a vertically-reciprocating ortraveling frame having plungers in its upper face'which play against andactuate the stripping device of the capsule mold-pin plate; and theobject of the invention is to i provide means for actuating'thestripping device of the capsule mold-pin plate, whereby the capsules arestripped fromthe mold-pins and placed in the cells or pockets of thereceiving-frame. This result is attained by the mechanism illustrated inthe accompanying drawings, in which-- showing the receiving-frame inposition above the mold-pin plate. N Fig. 4 is a vertical sectionondotted line was of Fig. '1. Fig. 5 is an enlarged detail, partly insection, to be referred to.

' As indicated in the drawings, the parts lettered A, A, and B representthe stationary or main frame of the machine.

T represents the vertically-reciprocating or traveling frame, which iscomposed of U- shaped sliding arms N, coupled near their free ends bythe cross-head H and the bars Z, which are bolted to and cross at rightangles the horizontal portions'of thearms N, said bars Z having mountedthereon the series of plungers n, as shown in Figs. 1, 3, and 4.

W represents the fly-wheel mounted on the outer end of the drive-shaftS, the inner end of said shaft being journaled in the frame of themachine.

F represents a supporting-frame for the shaft S, andD the drive-pulleyon said shaft.

Journaled in the base of the main frame of the machine is thecounter-shaft S, carrying at its ends the eccentrics E, which areconnected by the rods'd to the cross-heads H of the traveling frame T,(see Figs. 3 and 4,) said shaft S also carrying the sliding clutch C,which, by means of the 'treadle t, shaft t, and yoke Y, may be caused toengage with the large cog-wheel P, said wheel being loosely mounted onthe shaft S and meshing with the pinion P on the inner end of thedriveshaft S, the spring 2 drawing the clutch G from engagement with thecog-wheel'P when r the pressure is released from the treadle t, as shownin Figs. 2 and 4.

A are brackets secured to the uprights A of the main frame, saidbrackets receiving the threaded shaft Z of the sprocket-wheels m, and

over the reduced ends f of the hub f of said sprocket-wheels rests thefoot 0 of the supporting-legs L of the adjustable frame, said .legsbeing bolted to and supporting the adjustable frame D, which is composedof the rails R and B andthe upright pieces h, said frame being adjustedin height by turning the threaded shaft Z of the sprocket-wheels in thebracketsA", whereby the frame D may be raisedor lowered, as desired.

The employment of the chainbelt 0', passing around the series ofsprocket-wheels m and engaging therewith, enables the simultaneousturning of said wheels, the shaftZ of which is screwed into the bracketsA. Therefore the turning of one of said wheels by means of the wrench Kturns them all alike, thus uniformly raising or lowering the frame D,the idle sprocket-wheel m serving to tighten the chain belt U, and bymeans of the lever n is operated to give said chain the requiredtension.

K is a yoke, which is bolted to the bar F of the stationary frame (seeFig. 4) and extending upward, its forkedends W projecting horizontallytoward the front of the machine, and above the bars forming the top ofthe traveling frame T (see Figs. 1 and 4) engage the shoulders of thebuttons 2' in the under face of the mold-pin plate M, and assist inholding said plate in position when placed IOC 011 the upper face of therails R of the frame D, as shown in Figs. 2 and 4.

The operation of the machine is as follows: The mold-pin plate M, havingcapsules on its pins which have been previously trimmed, is slidsidewise onto the frame D. The shoulders 4 (see Fig. 4) of the legs Land the upright pieces h engage over the edge of said mold-pin plate.The forked ends W of the yoke K also engage the heads of the buttons 2'on the bottom of said mold-plate, and the dog d, which is held by thespring 5, (see Figs. 2 and 3,) is hooked over and secures the front edgeof said plate, whereby said mold-pin plate is securely held on the frameD and in position so as to cause the holes 6 in said plate to registerwith the plungers n in the upper face of the reciprocating or travelingframe T. The capsule-receiving frame R is then placed over the mold pinplate M and rests on the set-collars 3 on the posts a. (See Fig. 3.) Theupper end of the pins f, on which are formed capsules, project into thecells 0 of the adjustable bars of said frame R, as shown by dotted linesin Fig.

' (See also Fig. 5.) The receiving-frame R consists of a series ofparallel bars, with cells or pockets 0 formed in their joined faces.Said cells are enlarged by a separation of the bars. When the bars havebeen separated, the receiving-frame is placed over the pins of themold-plate, as before described. The bars of the receiving frame R arethen closed or moved together, thereby pressing slightly the capsules 0upon the capsule-pins f, as shown in Fig. 5. (The receiving-frameconstitutes another invention and is not fully set forth herein, as itis clearly explained in another application filed with this.) \Vhen thereceiving-frame is in position, as before stated, the operator throwsthe treadle 25 down, sliding the clutch into gear, starting theeccentrics, which impart an upward stroke to the traveling frame,thereby forcing the plungers n. through the openings 6 of the mold-plateM, striking the stripping-plate E, raising it and also carrying with itthe receiving-frame R. Theupward stroke of the eccentricsE is sufficientto carry the capsules 0 off the upper ends of the capsule-pins,leaving-them in the cells 0 of the receiving-frame. A partial removal ofthe capsule-plates is shown in Fig. 5. The frame R then being filled islifted from the machine. A further rotation of the shaft S carries thereciprocating frame T down to the position shown in Fig. 4, withdrawingthe plungers n from the holes e in the mold-pin plate M, when said platemay be removed from the machine, another replaced, and the operation offilling the receiving-frames continued, as before described.

As the stroke of the eccentrics is always the same, a varying in thelength of the mold-pins f for short or long capsules requires anadjustment of the upper supporting-frame D. In making large capsules thepins are longer, when the supporting-frame must be lowered to bring thepoint of the pins down to a position where the upward stroke of theplungers n will raise the stripping-plate E sufficiently high to freelystrip them, and in the use of shorter pins the frame D must be raisedaccordingly, as will be readily understood. The frame D is raised andlowered by means of the sprocket-wheels and chain-belt mechanismhereinbefore described.

Having thus fully set forth my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In a capsule-machine, the combination of the main frame, thetraveling frame, the mechanism for operating the traveling frame, theadjustable frame, and means for adjust ing said frame, consisting of thebrackets, threaded shaft, sprocket-wheels, and chain belt, substantiallyas specified.

2. In a device for the purposes set forth, the main frame, incombination with the drive and counter shaft-s, the pinions on saidshafts, the sliding clutch on the counter-shaft, the treadle mechanismto operate the clutch, the eccentrics on the ends of the countershaft,the traveling frame, the rods coupling said traveling frame to theeccentrics, the adjustable frame, the mold-pin, and strippingplates, theformer having holes to receive the plunger-pins of the traveling frame,as and for the purposes specified.

In combination with the main frame having the brackets, the series ofsprocketwheels, the shafts of which have threaded engagement with thebrackets, the frame mounted on the hubs of the sprocket-wheels, thewrench, the chain belt, and means for tightening said belt, as and forthe purposes
